Referring to the drawings in detail, it will The outer end of the rod 12 has connected 109 the arrows. faces 17 and a resilient, substantially U- thereto by means of a swivel joint 19, an extension 20 which is pivotally connected to a bracket 21 mounted on the free end portion of the sash 2 of the casement window. The swivel joint 19 permits rotation of the rod 12 relative to the extension 20 and this constitutes a very important feature of applicants invention.

In use, the parts are assembled in the manner illustrated in the drawing, and when it w is desired to swing the easement window, the rod 12 is rotated on the extension 20 in a direction to shift the resilient spreader 18 away from the cam surfaces 17 of the brake shoes 15. The pressure of said shoes against the inner Walls of the tubularsections 5 is thus reduced sufliciently to permit sliding movement of said shoes and the window may thus be swung to any desired position. The

direction of rotation of the rod 12 is then reversed in a manner to move the spreader 18 between the cam surfaces 17 and spread the shoes 15 into engagement with the inner walls of the tubular sections 5 and the sections of the rod are thus frictionally secured together in adjusted position. The shoes 15 are preferably retracted just enough to permit sliding movement of the same in the tubular section 5 but the same are preferably maintained in engagement with the walls of said tubular section 5 under .sufiicient pressure to permit rotation of the same with the rod 12. If desired, suitable longitudinally extending coacting ribs and channels may be provided on the shoes and the inner wall of the tubular section 5 to positively prevent rotation of said shoes with the rod 12.

The swivel connection '19 which joins the rod 12 to the supporting extension 20 permits the looking or unlocking of the shoes 15 while the opposite ends of the rod are secured to the sash and frame of the window, as will be apparent and, as'before stated, this is a a most desirable and important feature of this invention.

It is believedvthat the many advantages of a casement window retaining rod constructed in accordance with this invention will be readilyjunderstood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the etails of construction may be had which will fall within the scope of the invention as claimed.

\Vhat is claimed is A casement window retaining rod of the character described comprising a pair of mentary brake shoes mounted on the extension on diametrically opposite sides thereof and having opposed recesses therein for the reception of the flange, said shoes further having their opposed faces provided with complementary recesses having inclined cam surfaces, a resilient spreader member threaded for longitudinal movement on the extension and engageable with the cam surfaces in a manner to shift the brake shoes laterally to frictionally engage the walls of the cylinder, another extension swivelly mounted on the outer'end of the rod and a bracket hingedly connected to the free end of the second named extension and to the sash of the window.

In testimony whereof I affix my signature.
